Official HP False Paper jam reset

Introduction

Posting because I keep having to look it up...

Your HP printer says or is signalling (via lights or semaphore) that there is a paper jam.
You know and I know it is lying through it's roller teeth, and It refuses to budge from it's story.
Here's the drill.

Press the Power button to turn on the product.
With the product turned on , disconnect the power cord from the rear of the product.
Unplug the power cord from the wall outlet.
Wait at least 15 seconds.
Plug the power cord back into the wall outlet.
Reconnect the power cord to the rear of the product.
If the product does not turn on by itself, press the Power button to turn it on.

Conclusion

Yes, I too was surprised that this was actually a solution posted in various locations, and I was skeptical that it would work.
Then I was surprised and happy that it does indeed stop the printer from lying!

A vendor claims Ciscos hardware routers would out perform Sophos firewalls as gateway devices. Each vendor claims their stuff is superior. What do you think, is the hardware advantage enough to overcome the extra hop/processing cost?
